i Application filed hily n'Th'e invention relates to` spraying devices of that'type in which, the'fluid contents ofa receptacle is forced by pressure through a nozzle inthe forin of a spray. 'Y One of vthe objects of the invention is to provide an improved construction of spraying device which may be ymanufactured at comparatively low cost and operates in a highly satisfactory manner. lAnother ob]ect is to provide av spraying device with an expansible receptacle which. may be, readily inserted into. another receptacle and Vwhich may be readily and quickly drained. With these asv well as other objects in View the invention resides in the novel features of construction and lcombinations and arrangements of parts as more fully hereinafter'set forth.

The spraying device herewith shown has thereceptacle 1 which is preferably formed of sheet metal and is cylindrical'in vshapeand the eXpansible receptacle 2v which is preferably formed of rubber and 1s located within the receptacle '1. The receptacle 1 has the central fill :opening 3 in its vupp-er end which is adapted to be closed by the cap 4 in the nature of a sheet metal disk and located inside the receptacle, there being preferably Va gasket 5 formed of suitable inaterial such as rubber permanently secured to the outer face of the cap and engageable with the inner face of the upper end of the receptacle. 6 is a reinforcing ringperinanent-ly secured to the" outer face of the vupper end ofthe receptacle and' having its inner periphery registering with the fill opening 3 and 7 is a Vbar extending diametrically across the ring and engageable with the outer face thereof, this bar, being adapted to bey located by means of the pins 8 which extend through the upper end ofy the receptacle and the reinforcing ring and are adapted to extend through the ends ofthe bar. 9 is a suitable bolt extending axially through the cap 4 and centrally through the bar 7 and threadedly engaged vby the thumb nut 10 which upon tightening clamps the gasket 5 firmly against the inner face of the .end of the receptacle. 11 is a dischargepipe for 'thestem 16 of the fitting.'

This pipe 'extends through thesidewall offthe recepf tacle 1 `nea-r its lower fend and 'longitudinally within this recept'acle neaiits sideI wall and through the upper end thereof.' 21 is a Asuit'- able spring pressed valve withinthev-lower endl portion of the pipe`20`and adaptedl to permit the 'passage of fluidfunderpressure into this pipe` butprevent passage ofthe fluid in thefrev'erse direction. 22 is a pressure gage above the, upper end of the receptacle 1`and connected to the pipe 20 and. p23 'is transversefbranch of they pipe'` 20 lwhich is adaptedto beconnected to the fitting 15V by inean's of thecoupling24upon the branch 23 fandladapted yto thread upon J To provide Yfor the discharge` ofthe fluid .from the expa'nsible receptacle and therebyV permit thisvreceptacle to contract, I Vhave provided the fitting 25 which has apassage-` way extending through the receptacle 1 and communicating with theinterior of the ex-v pansible receptacle 2. This fitting is constructed to provide thel maximum size of discharge passageway with the minimum size of fitting and furthermore is so con-y structed that the expansibl'e receptacle may be readily removedv or reinserted into the` main receptacle.V In detail, the fitting has the pair of sections 26 and 27 Which are respectively located upon the inner vand outer sides of the expansible'receptacle 2 and are adapted to be clamped against the Wall of this receptacle. by means of the screws 28.

Y Suitable gaskets 29 Vpreferably formed of rubber are located adjacent the inner and outer sides of thel expansible receptacle to seal thehjoint betvveen' this receptacle and the sections 26 and`27. These sections have the axial openings 30 and 7431,'` respectively. 32 isa third section of the fitting which is locatedv at the outer side of the bottom of the receptacle l and is adapted to be clamped thereagainst'by suitable means such as the nuts 33 which are threaded uponthey studs 34 extending through the section 27 and iiXedly threaded in the section 26.
